TOPVERT G1/H1/P1 Series
E-35
Braking chopper fault
(bF) {25}
Switch off power supply wait until display off then on
again, If fault code is still displayed please return to
the factory.
PG error
(PG) {26}
Check the wiring of the PG feedback.
Check whether the motor is blocked
Phase-Loss protect or
capacitor aged
(PHL) {27}
Three phase imbalanced at
the input voltage or the drive
detects excessive ripple
voltage on DC-Bus
Caused of power source:
Check whether the power voltage is normal
Check whether the screw at the input power terminal
is tightened
Check whether the power source phase-lacking
Caused of smoothing capacitor:
Check whether the smoothing capacitors life is ended.
Current signal error during
stop
(CC) {28}
Reset the drive, if okay, then might be interference
noise come into the drive.
Return to the factory if previous method is not effect.
CPU error
(CPu) {29}
Electronics Circuit Fault
Switch off power supply wait until display off then on
again, If fault code is still displayed please return to
the factory.
Fan fault
(FAn) {30}
Check whether the cooling fan is blocked
Replace the fan
Analog input error
(AnI.) {31}
Check if the analog input signal is out of range
Over-Torque2 detected
(ot2) {32}
Check whether the motor 2 is overloaded
Check whether motor 2 rated current setting (Pr5-40)
is suitable
Check whether the Over-Torque2 detect parameter
are suitable (Pr5-21~Pr5-23)
Check whether the mechanical system is normal
Increase motor 2 capacity and replace the drive with
the next higher power model
Motor overload
-Thermal relay 2
(oL2) {33}
(Electronic thermal relay 2
protection.)
Check whether the motor 2 V/F setting proprer
Check whether the motor 2 running low speed for long
period
Check for possible motor 2 overload
Check motor 1 full load current (Pr5-40)
Check electronic thermal overload 1 setting (Pr5-45 to
Pr5-46)
Reduce the load so that the drive output current does
not exceed the value set on Pr5-40
Increase motor capacity
Motor select error
(rnot) {34}
Check the motor wiring connection
Check the parameters settings
Low voltage on DC-Bus
during run
(LUr) {36}
The drive detects that the DC
bus voltage has fallen below
its minimum value during run
Check whether the input power voltage is normal
Check whether the power supply capacity is enough
Check for possible sudden load
Whether the 3-phase model is of the single-phase
power input or the phase-lacking
Check whether the Inrush limit by-pass circuit fault
Check whether the input power was interrupted
Check whether the input side magnetic contactor is
normal
Low voltage on DC-Bus
(LU) {39}
The drive detects that the DC
bus voltage has fallen below
its minimum value
